Patented Oct. 3, 1950 WAGON-BOX ELEVATING AND TILTING DEVICE Clark F.Walsh, Charles City, Iowa Application December 29, 1945, Serial No.638,341

The present invention relates generally to a novel and improved wagonbox elevating and tilting device, but more particularly to a simple andimproved construction adapted to be attached to the conventional type offarm wagon so that the front end of the box carried thereon may beelevated to the desired height to dispense or dischargesubstantially-the complete contents therefrom by gravitation. i

A further object of the invention is to provide a novel and improvedconstruction of a, wagon box elevating and tilting device in combinationwith a conventional type of hydraulic jack or lift so that the jackthereof may be easily and quickly attached thereto ordet ached therefromso that the same may be used in connection with successively elevatingand tilting any number of wagon boxes. which are suitably equipped tosupport the jack thereon.

A still further object of the invention is to provide a novel andimproved. telescoping arrangement for supporting therein a conventionalpost type hydraulic jack and means whereby the jack may pivot and beadjusted with respect to the wagon box so as to support, elevate andtilt the front end of the wagon box for discharging the contentstherefrom.

These and other objects are accomplished by providing a construction andan arrangement of the various parts in the manner hereinafter describedand particularly pointed out in the appended claims. I I

Referring to the drawings:

Fig. 2 is a similar side elevational view showing the manner in whichthe wagon box is partially tilted b raising the front end thereof;

Fig. 3 is a fragmentary top plan view showing the construction forsupporting the jack thereon, with the jack removed; a

Fig. 4 is a cross sectional view taken on the line :ll in Fig. 1;

Fig. 5 is a fragmentary front elevational view showing the wagon box andjack in its lower most position; and i Fig. 6 is an enlargedlongitudinal cross sectional view showing the manner in which the posttype hydraulic jack istelescopica-lly mounted in the sleeve-like socket.

In illustrating one form of my invention, I have shown the same inconnection with a conventional form of farm wagon which comprises 8Claims. (01. 298-19) supporting wheels I t and 1!, suitable axlestherefor and a connecting .briefiy, front and rear reach !2 between thefront and rear axles. The front axle portion of the wagon is providedwith the usual transverse bolster or beam 13 to which isv secured theusual forwardly projecting and horizontally spaced stub-tongue membersM. Supported on the wagon frame in the manner well understood in theart, is a wagon box generally indicated by the reference character H:which consists of a bottom l6, side walls I! and front and rear endgates l3 and I9. Secured to the lower surface of the floor it of theWagon box adjacent the forward end is the usual transverse cleat 2il.

My improved unit which is adapted to support a hydraulic lift or jacktherein and which may be mounted on any type'of conventional farm wagon,comprises a transverse wood beam 2! which is adapted to be mounted onand clamped to the transverse beam It by means of clamp brackets 22 andclamping bolts 23. Secured to the underside of the transverse beam 2! isa forwardly projecting member or plate 24. Secured to the opposite edgesof the forward portion of the plate 24 are spaced apart vertical walls25 forming a channel-like arrangement at the front end thereof. Mountedin a threaded aperture 28 at the forward end of the plate 2 5 is athreaded bolt 21. The upper end of the bolt '2'! has a hand grip 29. Thelower end of the bolt is provided with annular recess and upset head 3|so as to swivelly engage a transverse channel member 30. From the abovedescription it will be readily seen that by adjusting the hand screw 29,the forward end of the plate 24 may be raised or lowered with respect tothe transverse channel member for tilting the position of the hydraulicjack in adjusting the same with respect to the front end of the Wagonbox. It will also be noted that the transverse channel member 39 restsupon the opposite-stub tongue member l4 and is free to slide withrespect thereto as well as pivot about the lower end of the bolt 2? whenthe front wheels iii are turned with respect to the frame of the wagon.The pivotal movement of the transverse member 38 is limited by means ofupwardly and vertically extending pins or bolts 32 which have theirlower ends mounted in suitable threaded apertures in the member 3!]. Asthe member 39 swivels about the lower end of the bolt 21, these pins areadapted to engage the vertical sides 25 of the plate 213 in the turningmovement. Pivotally mounted between and to the opposite sides 25 of thechannel member is a vertically extending socket or pipe 33. The pipe 33is pivoted to the side wall members by means of a transverse bolt 34which extends through a tubular member 35 mounted in the diametralopening 36 in the sleeve 33. Secured to the forward end of the wagon boxand embracing the lower side and forward edge of the transverse cleat 20is a reinforcing angle member 31. Extending through the wagon bottom It,the c1eat'20 and the lower flange of the angle member 31 is an eye-bolt38 which forms the connection for a hook of a link connection 39 to thejack in the manner hereinafter described.

The units or parts thus far described are adaptable to be mounted on anyconventional type of farm wagon so as to form the supporting structurewhich will permit a conventional hydraulic jack, generally indicated bythe reference character 40, to be removably supported therein forelevating the front end of the wagon box for discharging the contentsthereof from the rear end. This arrangement permits the jack to beeasily moved from one wagon to another when they are equipped with thesame apparatus to support and accommodate this jack.

The hydraulic post-type jack, as indicated at 40, is of the conventionaltype, but is preferably of the form disclosed in the L. C. Nilsonpatent, No. Re. 21,112, granted June 3, 1939. For further details of theconstruction and operation of this jack, reference to that patent may behad.

The jack 40 comprises briefly, a vertically reciprocatable sleeve-likehand operating member H which, in turn, elevates a sleeve 42 on ashaftlike member 33. The shaft-like member has its lower end adapted torest upon the transverse tubular member 35 and bolt 34. Secured to thelower end of the sleeve member 42 is a collar 44 which is adapted toreciprocate or move within the inner bore 45 of a telescoping sleeve 46which, in turn, is telescopically and removably mounted in the socket33. When the sleeve 42 attains a certain height, the collar 44 securedon the lower edge thereof engages a shoulder or internal flange 41formed on the upper end of the telescoping sleeve 46. Secured to theintermediate portion of the tubular member 42 is an adjustable clampbracket 48 which may be adjustable vertically and securely clamped by aclamping screw 49. Formed on the rear side of the bracket 48 is a hook511 to which the eye 5| of the link connection 39 may be attached.

Summarizing the advantages and function of operation of my improvedwagon box elevating and tilting device, it will be readily seen that byproviding or equipping each conventional wagon with a socket or sleeve33, together with th necessary attachments for supporting it inposition,

it is then possible to quickly detach or attach the post-type hydraulicjack 49 from one wagon to another, thereby obviating the necessity ofhaving more than one jack for performing the function of discharging thecontents from each wagon box and by providing an adjustment so that thejack socket 33 may be adjusted vertically to accommodate the jack M]with respect to the box. This novel arrangement provides a very simpleand efficient means for this purpose at a .minimum cost. If an operatordesires to raise the box to an elevation higher than that shown in Fig.2, suitable blocks or supports may temporarily support the raised boxwhile the lower end of the hook link 39 may then be transferred to asuitable aperture provided in the lower flange of the transverse anglemember 31 to elevate the box an 4 additional distance from that shown inFig. 2 of the drawings. In this connection it will also be noted thatthe upper end of the sleeve 33 is beveled or tapered as shown at 33' soas to permit the forward edge of the angle member 31 to freely slidethereover in the operation of lowering the front end of the wagon box.
